This patch set will enable LoongArch virtual machine in edk2, the new
LoongArch virtual machine is located in OvmfPkg/LoongArchVirt/, it is a
generic platform that dose not require any actual hardware.

Patch1-Patch14: Submit the common library and driver for LoongArch
virtual machine and real hardware. Such as base help functions,
exception handel, MMU library, multiprocessor library etc.

Patch15-Patch16: Add PrePiCpuIoSize for LoongArch64. and move ArmVirtPkg
two PCDs into OvmfPkg for easier use by other architectures.

Patch17-Patch29: LoongArch virtual machine private code, include SEC and
PEI phase code, some library and drivers.

Modfied modues: MdePkg, UefiCpuPkg, EmbeddedPkg, ArmVirtPkg, OvmfPkg.

Chao,
MpInitLib is to avoid code duplication between CpuMpPeim and CpuDxe.
If you only need MP protocol but not MP PPI, do you still need to add MpInitLib?
Can MpInitLib code be included in CpuDxe folder?

Thanks,
Ray

Subject: [PATCH v1 00/29] Enable LoongArch virtual machine in edk2

This patch set will enable LoongArch virtual machine in edk2, the new
LoongArch virtual machine is located in OvmfPkg/LoongArchVirt/, it is a
generic platform that dose not require any actual hardware.

Patch1-Patch14: Submit the common library and driver for LoongArch
virtual machine and real hardware. Such as base help functions,
exception handel, MMU library, multiprocessor library etc.

Patch15-Patch16: Add PrePiCpuIoSize for LoongArch64. and move ArmVirtPkg
two PCDs into OvmfPkg for easier use by other architectures.

Patch17-Patch29: LoongArch virtual machine private code, include SEC and
PEI phase code, some library and drivers.

Modfied modues: MdePkg, UefiCpuPkg, EmbeddedPkg, ArmVirtPkg, OvmfPkg.

18478 lines seem overkill... Probably too much code added / duplicated
under UefiCpuPkg, as Ray says.

Also:

- Please make sure you post the patches with the "sendemail.thread" git
config item set to "true". "BaseTools/Scripts/SetupGit.py" takes care of
that. Otherwise, just as it has now happened, your patches are not
threaded under the cover letter; they fly apart as independent messages.

- Whenever you post a (new or initial) version of a patch set, please
link the URL of the cover letter (from the mailing list archive) into
the Bugzilla ticket, in a new comment.

Thanks
Laszlo

Hi Ray,

Thanks for review.


I think the MpInitLib is necessary, because this library will serve PEI 
and DEX phases. In LoongArch, the MP initialization function will be  
called first in the PEI phase. It will wake up all of AP, collect 
accurate online cores, and all APs will fill in their self information 
to prepare for next wakeup.

The second time the MP initialization function is called will in DXE 
phase, usually located CpuDxe, I guess you are checked this code. This 
time the MP service HOB will be brought from PEI to DXE phase, and the 
MP protocal will be registered to prepare for service DXE phase.

Like you saied, why not use the MP PPI? I think it's just that the code 
hasn't been added yet, and I think LoongArch will definitely need the MP 
PPI in the future, like memory trainning, configure APs local registers, 
etc.


Thanks,
Chao

Hi Laszlo,

Sorry, the reason of some mail is not under cover letter is found, I 
will fix it at the V2.

I don't think the code is **duplicated** since most code is architecture 
related, and maybe some code is referenced from others ARCH. As  the 
cover letter saied, most code is distributed in MdePkg, UefiCpuPkg, 
OvmfPkg. MdePkg is added some help functions for LoongArch. UefCpuPkg is 
added CpuTimerLib, CpuExceptionLib, CpuMmuLib, MpInitLib, CpuDxe. Each 
library and driver is not small. OvmfPkg adds the private code for 
LoongArch QEMU virtual machine instances, it override some architecture 
related library that cannot use the publice libraries, mostly for the 
PEI phase.


Thanks,
Chao

It is necessary for physical machine like memory trainning/configure APs 
local register etc, however I doubt whether it is useful for LoongArch 
virt-machine, I do not see the advantages for wakeup APs in UEFI BIOS. 
ACPI FADT table is prepared in qemu side rather than BIOS side.

Hi Bibo,

Yes, you are right, MpInitLib is most used on the physical machines, but 
in LoongArch, this library is a public library, so it is the minimum 
requirement that it can worke on physical machines and virtual machines. 
This library has been tested on the actual and virtual machines to 
ensure it works right.


Thanks,
Chao
